Proposing making immutable by default in C or C++ doesn't make sense due to backwards compatibility reasons. New languages like Rust have easier time making better choices with immutable by default.

They could just add a "use immutable;" directive that you place at the top of your file.

C# does this with the null hole. I wish more languages would take a versioning approach to defaults at the file-level.
